UNITED STATES PATENT OFFICE.

SPINDLE.

Application filed January 19, 1924;. Serial No. 687,317.

To all whom it may concern:

Be it known that I, Ronnn'r IV. DoNLnY, acitizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements, in Spindles, ofwhich the following is a specification.

This invention relates to improvements in thread holding devices for usein cotton or textile mills, the general object of the invention being toprovide improved means for supporting the thread holder so that it canrotate with the least amount of friction.

Another object of the invention is to provide means for easily andquickly detaching the holder from its support.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing my invention in detail, ref erence will. be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in whichs- Figure1 is an elevation of the improvement.

Figure 2 is a longitudinal sectional view. Figure 3 IS a section on line3--3 of Figure 2.

Figure l is a section on line 4:-4: of Figure 9'.

In these views, 1 indicates a part of the main platform of the machineto which the attachment is applied and 2 indicates the supporting memberwhich passes through a hole in the platform and is threaded to re ceivethe base 3 and the nut 4 which clamps the support to the platform. Apassage 5 extends longitudinally through the support and a grease cup 6is threaded to the lower end of-the support so that when the cup isturned the grease therein will be forced through the passage 5. Theupper end of the support is formed with a recess 7 to form a seat for aball 8. The thread holder A consists of the spindle 9 and a hollowpulley member 10 which receives the upper end of the supporting memberand rests upon the ball 8 so that the member A is 1'0- tatablysupported. It has an annular groove 11 adjacent its lower end which isengaged by a latch member 12 carried by the spring strip 13 which isfastened to the base 3, the latch member being provided with a handle14- so that it can be pulled from the groove when the member A is to beremoved.

From the foregoing, it will be seen that the holder A is supported sothat it can rotate with practically no friction and lubricant can besupplied to the parts by tightening the cup 6 to force the lubricantthrough the passage 5 to the ball seat. The holder can be easily removedfrom the support by pulling the latch member outwardly by its handle.The spring strip 13 acts to hold the latch member in engagement with thegroove. The part 10 acts as a pulley for receiving the driving belt.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in' theconstruction and in the combination and arrimgement of the severalparts, provided that such changes fall within the scope of the appendedclaim.

What I claim is A device of the class described comprising a tubularsupport having a ball seat at its upper end and a threaded lower end, anut engaging the screw threads for attaching the support to a platform,a grease cup threaded to the lower end of the support and adapted toforce lubricant through the support to the ball seat, a ball in theseat, a holder having a socketed pulley member at its lower end forreceiving the upper part of the support so that the holder will restupon the ball, said pulley member having an annular groove adjacent itslower end and a latch member connected with a part on the support andengaging the groove.

In testimony whereof I affix my signature.

ROBERT W. DONLEY.
